Question
What is the difference between:
Strong electrolyte and weak electrolyte.
Solution
| Strong Electrolytes | Weak Electrolytes | |
| (1) | Electrolytes which allow a large amount of electricity to flow through them. | Electrolytes which allow small amounts of electricity to flow through them. |
| (2) | These are good conductors of electricity. | These are poor conductors of electricity. |
| (3) | These are almost completely dissociated in the fused or aqueous solution state. | These are partially dissociated in the fused or aqueous solution state. |
| (4) | These solutions contain (almost) only free mobile ions. | These solutions contain ions as well as molecules. |
| (5) | Examples: | Examples: |
| Acids: Hydrogen chloride, Sulphuric acid, Nitric acid, etc. | Acids: Carbonic acid, acetic acid, oxalic acid, etc. | |
| Bases: NaOH, KOH. (aqueous or molten state) | Bases: Ammonium hydroxide, calcium hydroxide. (aqueous or molten state) | |
| Salts: NaCl (molten or aqueous), PbBr2 (molten), CuCl2 (aq.), CuSO4 (aq.) | Salts: Ammonium carbonate and lead acetate. |
